The heated race to become the Democratic nominee for Pennsylvania lieutenant governor is taking an unusual turn as incumbent Mike Stack and challenger Nina Ahmad begin hitting the airwaves in the Philadelphia region.

At a recent monthly meeting, the Philadelphia Board of Ethics endorsed legislation that would bring a raft of critical changes to the city’s campaign finance laws and limits.

Most notably, the bill would shift the city away from annual campaign finance limits and to a system of limits based on four-year election cycles – while increasing the maximum allowable contribution during that period to $5,000 for individuals and $20,000 for businesses and other organizations.
